A orney Patented Apr. 28, 1953 UNITED STATES PATENT OFFICE WINDOW Beniamin M. Altwies, Fostoria, Ohio A pplication December 6,1948, Serial No. 63,800 I l v (01. 20-522) 2 Claims.

7 l This invention relates to windows and has for its principal object the provision of a unit that can readily be placed in position in the windowopening of a building and may carry two or more sashes preferably with metal frames in which the operation of the sashes is more convenient and positive and in which any or all of the sashes may readily be removed by one not familiar with tools. I

An important object of the invention is to provide an improved ribbed track, one portion of which may be permanently secured in place and the other may be held solely by the window frame and the sashes. A further object is to provide a screen sash so located that it can readily be moved from the usual summer position to a storage space in the window unit and the upper sash may be latchedin normal raised position unaffected by the raising or lowering of the screen sash. An incidental object is to provide a spring latch for each of the two glazed sashes for convenient locking of either or both of these sashes in normal position with means for readily and easily releasing either sash.

Other objects of the invention concern details all of which together provide a more satisfactory window, one which will give long service without any attention. Still other objects of the invention are pointed out in the claims.

Iri the drawings:

Figure 1 is an exterior elevation of the window.

Figure 2 is a central vertical section.

Figure 3 is a partial horizontal section.

Figure 4 is a corner elevation partly broken away.

Figure 5 is a side view of Figure 4. Figure 6 is a section on line 66 of Figure 4.

' Figure 7' is a perspective view of a stile and a rail before assembly.

Figure 8 is an inside elevation of the lower sash lock; Figure 9 is a side elevation of the lower sash lock; Figure 10 is a horizontal sec-' tion view thru the lower sash lock; Figure 11 is an edge view of the track; Figure 12 is a side view of the track; Figure 13 shows a modified form of leaf spring and the cutaway at the top:

of the screen sash; Figure 14 illustrates a modias being moved part way into the storage spacefor it, located behind the upper sash 14.

Referring now particularly to Figure 2, each of the sashes has a top rail ll. Where it is convenient to distinguish between the various rails the top rail of the upper sash will be denoted l8 and specifically the check rail of the uppersash is I8u, the bottom rail of the lower sash I is ill and the check rail of the screen is I88.

These various rails may be of identical cross section but I prefer that the top rails 11 of the upper sash and the screen sash shall'be smooth but the top rail lab of the lower window shall correspond in cross section to the three check rails [8 having a slight bulge toward the adj acentv sash so that the three sashes fit snugly together as best seen at the center of Figure 2. The bottom rail IQ of the lower sash is identical with the rail l1 except that it carries a convenient finger piece l9a. for ease in raising and lowering this sash which obviously is the most used. The upper.

and the lower sashes each carry a pane of glass 20 and the screen sash carries wire cloth 2!.

It is convenient to secure the wire cloth in the screen sash [6 by means of a vinyl rod 22 altho any other plastic material having the same properties could be substituted. The rod is made of suffi-cient softness so that the screen material 2|.

is at least partially imbedded in the rod 22 when the rod is driven in place in the channels of the rails and stiles of the screen sash It. Once this rod is driven in place it remains in firm con-. tact with the wire netting and the sash frame,

keeping the wire cloth taut.

Referring particularly to Figure 3, inside of the frame member I l is an upper track 25 having three ribs 26 integral with and equally spaced on the track back 2'1.

inward a bit more than its own thickness from fied form of pull for the screen sash; Figure 15' I is aseotion'thru thernodified form which is shown in elevation; Figure l6shows a modified form of triple track.

--My window includes a frame top or head It) and two frame sides H, all three being of iden-..

tical cross section and a bottom rail l2, of sill shape. In this frame are mounted a top sash M, a bottom or lower sash l5, and between these islocated a screen sash l6, in-Figure 1" shown 1 of spring 3| maybe seen in Figure 4 indicating the spacing edge 28 of the track 25. The several. stiles are denoted by the numeral 3!] and specifically the stile of the .upper sash is 3M, the stile of the screen sash is 30s, and the stile of the lower sash is 301). Each ofthe stiles 3c carries, a plurality of spaced bowed springs 3 l the smaller, sashes carrying but two while the larger may.

carry as many as six on each side. An edge view that it is fiat strip material. One end of each spring may be secured to the stile in any manner as by spot weldingor riveting, for example, so

that its center bears against the edge of therib- 26. By means of these springs. each sash is con- One of the ribs is flush with. one edge of the back while the far rib is spaced 31 integral with the frame side II and formed of a portion of its side 33. This bracket is riveted as at 38 to the frame head I6. It is convenient to indicate the several portions of the .crossssection of the frame pieces I6 and .I I, both being made from the same extended or rolled form, The top or side of this form is given the numeral 33 and has two down-turned lips, a front lip 34 and a rear lip 35 between whicharereceivedthe track at the twosides. Integral with the frame section side 33 is a wide panel36 which wemay call the frame face. The rivets 32, which may be spot-welds, pass thru the :front lip 34 of the sidepiece II and thru the verticalframe face '36 of the frame head 10.

To secure the upper-sashin place there .is -.an opening thru both the upper .track25 and the side :33 ofthe side frame II. A longleaf spring 4| is secured to the :frame side .-I I -as-at 4'2 and its free end carries a pair of spaced latches 43 which project thru the opening 46 to engage an angularnotch 44 cutfin the upper sash stile. As the upper sash is raised it will cam the spring away and will :lock itself in position when the spring 4-! moves :to the normal position shown in full lines in .Figure 4. Therscreen sash can move freely between the two spaced latches 33 but when the lower sash (which has no notch) is raised it will cam the spring outward into the dotted.lineiposition shown in Figure 4 at which time either sash-can .be moved. .The :lower sash is'notlatched in upper positionand can be freely moved outward no matter what the position of the upperlsash imay Joe. Sometimesit is convenient to save a bit :of metaliand merely .turn the treeend of thefspring. inward. In thisicase, how ever, the screen :sash must he cut-away at the top following the sloping vline of .the notch -44 and then vertically upward. :It is sometimes convenient to bevel or round off #the upper corner of the lower sash the .more conveniently to cam thespring outward whether it be a.fiat:piece or have thectwo latches.

A veryiconvenientmanner of forming the corner of each sash is to :cutioii the =twoxchannel members fill .of 'therailsection :I;'I leavinga :tenon SI thru which a'hole 52 is formed. This .tenon SIiGGS fIGIYJiIlthBISIOt 54in the stile 30-being formed ;by side members and the central bar 55, which -:divides .the stile :into the larger channel section 54 -.and .the smaller section 56, having the two inwardlydirected lips :57 between whichis received :snuglytherib 26;of the .track'ZS. When the tenonfil ris snugly engaged in "therecess 154, the side metal of the :stile iis punched :into the hole 52 on ea'chfside, as indicatedby-thenumeral 58, dotted iinlFigure 7 to show that the indentation 5 8 has :not yet lbeen :made.

It is sometimes convenient to :latch =.the .lower sash in'place independently of the :nther sash-or sashes. A convenient'ilatchis shown'in Figuress,

9 and '10 and consists :ii'ierely 'inra :small plate 6.9 loose and preferably ispaced n bit1from vthe plate 36 ofthe frame piece I I but pivotingprzcamm'ing. malt. The: iate istbent inwardlyias :at Miami 4 terminates in a finger piece 62. It has a hole thru which a rivet 65 loosely passes, the rivet being anchored in the side member 33 of the frame. A spring 66 preferably of spiral shape engages the rivet 65 and holds the late against the frame member so that the inturned portion 6| slips in a notch 68 in the frame and in the sideof the stile .30 which -in this pase would iibe the lower sash and consequently given the "number 30b. The lower sash is readily moved by merelypressing the, finger piece 62 to the right as seen in Figuresfi and 10.

For convenient movement of the screen sash we thereiistprovided a pull-down member 80 having a stem 8| projecting loosely thru a hole in the lower screen rail Us and having a head 82. The :finger portion of this pull-down and lock is rectangular in section, as can be seen from the dottedpcsitionfidat.the bottomof Figure .2. in thisdotted .lineposition the pull-down and lock has passed-thru :anopening .815 inthe sill member I2 whichit may freely do but when the pull-down 1. is turned at right angles .it will lock the screen in lowered position since .the portion BI is free to rotate. It will .be noted .that each .of the .three sashes has aseparatelock of its .own and any one of the three canbe operated independentlyeof the other .two.

Inorderto make it possible .toremoveanyone of .the sashes at will, .the track is made .in .two sections, the upper ;.por.tion '25 of which is permanentlysecured .to the frame while theilower section 70 is entirely 'loose but is held .in place against the side .member 133 of the .frame .piece I I .by pressureof the spacing springs M. The upper portions 25 .of the trackiextendsffrom the top just aTlittle'less than half way of the frame opening and the vthreeribs areicut oftsharplyas at 12 and the back 21 of the track is beveled as .at I3 to a, sharp edge 14. The .lower track section lilis'beveled at '75 corresponding to the slope of I3 anditspointed .end'lii is rounded as best seen in Figure 6. "The 'beveling of the lower track leaves the .ribs 25 unsupported :at their iree ends, .thefback .of the track being cut o'fias at .Tlso that it is the ends of ltheribs only that are roundedas at [6. Thel'function .o'fithese parts willbest be understood from .a description of the assembly of the device. 4

The three members of the frame are cut from arolled section, the head Ill being assembled with the two side pieces .II by bending down thebracket piece 31 and spot-welding .or riveting it to the-side of the head I6, the side in this case being Ihorizon'tal. The sill portion I2 completes the .frame. ,Next the springs M are attached to the frame and the two upper tracks 25 arepermanentlyattached to lthe Lframe extending a (little 'less than half the way down. The frame with its --track and spring .is .now turned .upside .down and the -.upper sash, .the screen sash, and .the .lower :sash are placed .in the frame assemb1y,.-naturally upside down. .The two bottom tracks 10 are now pushed implace, the rounded end =76 aiding :in sliding .the lower section 1.0 into position, and the unit is complete. fI-he sashes so assembled .are ;-held .firml-y iniplace :but .can be;.pu1ledloose by first careiull-y lifting out the lower ends of "the bottom track sections III .for sexample vrafter zthe window is in position .in the home. The outside ribs .16 of the tracks :are :not iused if -.there is no screen but when the :screen is 'used it'ainvariably slides on the center :ribs .26.

if. the housewife wishes -.-to remove anysash,

she merely elevates all three of the sashes to their uppermost position where they will easily be held by the spacing springs 31 even in absence of the upper sash lock 43. By gently pulling the bottom ends of the lower tracks 16 away from the frame they can be lifted out and then whichever sash is to be removed is lowered to its bottom position. As can be seen from Figure 3 this lowered sash can readily be pulled laterally, that is, inside of the room since the sash well clears the side rear lips 35 of the frame member. The preference is to make all of the metal pieces of aluminum but the tracks and spring 4| could be of steel, altho usually not, and the springs 31 and 66 would usually be of this material, and cadmium plated. In Figure 4 the spring 3| is shown as placed in a slot 87 in the stile, avoiding the need to spotweld.

In Figure 13 a modified and often preferred form of leaf spring is illustrated. This spring 4| (1 is of aluminum, about four inches long, and is welded to the frame. As previously mentioned, when this type of spring is used, the screen sash is cut away as at 88 and 89 and the lower sash is beveled as at 90 to form a camming surface.

In Figures 14 and 15 is illustrated a modified form of pull for the screen sash. This pull 80a has a threaded connection 93 with the screen check rail 18s and a reduced stem 94 which is caught by a latch 95 pivoted as at 96 to the sill or bottom rail 12 of the frame.

Figure 16 shows a modified form of triple track in which the ribs are a bit thinner and a relief of about .009" is provided at the usually flush side.

What I claim is:

1. In a window construction comprising a frame having spaced parallel vertically extending side members, a pair of upper and lower track sections arranged in end-to-end alignment inwardly along each frame side member and each comprising an outwardly facing base portion and a plurality of vertically extending parallel rails projecting inwardly of the frame, upper and lower sash members each having an area approximately one-half the area of said frame each slidably mounted on one of the rails of said track sections for vertical movement relative to each other in said frame, the upper track section of each pair being fixedly secured to the frame side members and having the lo er end portion cut away and tapered downwardly and out ardly of the frame and terminating above the bottom edge of the sash members in the raised position thereof, the lower track sections each having the upper end of its base terminating short of the rails which pro ect therebeyond and are tapered 1 pwardly and inwardly of the frame for complementary overlapping engagement with the tapered lower end portion of the upper track section, and the extremities of the tapered upper ends of the rails of the lower track sections constituting cam portions for en agement with the tapered lower ends of the upper track sections to guide the upper ends of the lower track sections upwardly into positions intermediate the opposite side portions of the raised sash members and the tapered lower ends of the upper track sections as said lower track sections are moved outwardly into position against the frame side members when inserted therein.

2. In a window construction comprising a frame having spaced parallel vertically extending side members, a pair of upper and lower track sections arranged in end-to-end alignment inwardly along each frame side member and each comprising an outwardly facing base portion and a plurality of vertically extending parallel rails projecting inwardly of the frame, upper and lower sash members each having an area approximately one-half the area of said frame each slidably mounted on one of the rails of said track sections for vertical movement relative to each other in said frame, the upper track section of each pair being fixedly secured to the frame side members and having the lower end portion cut away and tapered downwardly and outwardly of the frame and terminating above the bottom edge of the sash members in the raised position thereof, the lower track sections each having the upper end of its base terminating short of the rails which project therebeyond and are tapered upwardly and inwardly of the frame for complementary overlapping engagement with the tapered lower end portion of the upper track section, the extremities of the tapered upper ends of the rails of the lower track sections constituting cam portions for engagement with the tapered lower ends of the upper track sections to guide the upper ends of the lower track sections upwardly into positions intermediate the opposite side portions of the raised sash members and the tapered lower ends of the upper track sections as said lower track sections are moved outwardly into position against the frame side members when inserted therein, and spring members mounted at opposite sides of said sash members and engageable with the rails of said track sections to maintain the sash members in their proper position relative to said track sections and to secure said sashes in any desired position relative to each other within said frame.
